Title:
METHOD FOR MANUFACTURING GRID-STIFFENED STRUCTURE AND GRID-STIFFENED STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/168555
Kind Code:
A1
Abstract:
A method for manufacturing a grid-stiffened structure 1 is provided with: a step of regularly arranging triangular or square cells on one surface of a sheet member 10 and setting a lattice-shaped pattern having rib constituting regions 141 between the cells; a step of providing through-holes 15 in places at which the rib constituting regions cross each other in the sheet member to segmentalize the rib constituting regions; a step of folding the rib constituting regions of the sheet member to form ribs 121, 122, and 123 protruding from the one surface of the sheet member; and a step of connecting ends of the ribs to each other at the positions of the through-holes.
